This largely depends on how one defines pi. I believe that the concept of R^n (Euclidean space) exists even in entirely different physical spaces. This is because Euclidean space represents a universally recognized idea of simple space in terms of curvature. For instance, in any world, the concept of '0' represents simplicity. In this context, pi will always remain constant.
